Abstract

Based on a damping control strategy for oscillation energy descent, an adaptive UPFC fuzzy-logic damping control scheme is proposed. Using the UPFC line power as the input signal, the controller can adaptively adjust the control parameters according to the magnitude of power oscillation in the UPFC line using fuzzy rules to effectively damp the power oscillation. One of advantages of the controller is that the detailed model and parameters of systems is not needed in the controller design. Case studies on the 10-generator New England test system show that the controller can effectively enhance dynamic stability of systems with good robustness.
